Reaction of 1,3,5-tris(dimethylamino)benzene (TDMAB ) with 1,2,3,4,5,6-hexacyanobenzene (HCNB) in acetonitrile solution gives - depending on the crystallization method - two different products: dark needles of a 1:1 (1) and black compact crystals with a metallic lustre of a 2:1 (2) charge transfer complex. 2 crystallizes in the triclinic space group P1 , Z = 1, a = 9.9489(22), b = 10.0555(21), c = 10.1418(20) Å , α = 115.006(16)°, β = 102.820(17)°, γ = 93.647(18)°, V = 882.3 Å3, dc = 1.2 g cm-3, measured at room temperature, R = 0.053 for 2670 observed independent reflections and 301 parameters. The structure contains isolated “trimers” of one HCNB acceptor which is “pancaked” by two TDMAB neighbors. The arrangement of these trimers in the lattice results in alternating HCNB and TDMAB sheets. The solid is diamagnetic.1 could not be obtained in crystals suitable for a single crystal X-ray investigation. Its paramagnetism which is observed immediately after preparation disappears in the course of several days.

Close Contacts

Solid-state Diels–Alder reaction in a 2 : 1 donor to acceptor charge-transfer complex leads to a synthetic co-crystal composed of product and unreacted donor. Analysis of close contacts and DFT energy calculations indicate that the reaction occurs cooperatively where the arrangement of molecules shown in (ii) is favoured.

The compound [C7H7][C5(CO2Me)5] forms very long but thin orange-red needles, which, in contrast to a previous report, form orange-red to deep red solutions in polar solvents. Decolorization of an acetone solution occurs on standing, but the white compound so obtained has not been identified. Single-crystal X-ray structure determination at 295 K (R = 0.078 for 1030 'observed' reflections) shows the presence of an infinite sandwich structure comprising columns of interleaved anion and cation planes normal to b. Crystals are rthorhombic, Pbcn , a 18.206(6), b 13.954(12), c 17.243(5)Ǻ, Z 8.
